Safety and Efficacy Study Evaluating TRx0237 in Subjects With Behavioral Variant Frontotemporal Dementia (bvFTD)
Study Details
Study Description
Brief Summary
The purpose of this study is to demonstrate the safety and efficacy of TRx0237 in the treatment of patients with behavioral variant frontotemporal dementia (bvFTD).

---|---|
Experimental: TRx0237 200 mg/day group
|
Drug: TRx0237
TRx0237 100 mg tablet will be administered twice daily.
|
Placebo Comparator: Placebo
|
Drug: Placebo
Placebo tablets will be administered twice daily. The placebo tablets include 4 mg of TRx0237 as a urinary and fecal colorant to maintain blinding; hence, the placebo group will receive a total of 8 mg/day of TRx0237.

Outcome Measures
Primary Outcome Measures
- Change from Baseline on Addenbrooke's Cognitive Examination - Revised (ACE-R) [52 weeks]
- Change from Baseline on Functional Activities Questionnaire (FAQ) [52 weeks]
- Change from Baseline on whole brain volume (assessed by brain MRI) [52 weeks]
Secondary Outcome Measures
- Change from Baseline on Unified Parkinson's Disease Rating Scale (UPDRS Parts II and III) [52 weeks]
- Change from Baseline on Frontotemporal Dementia Rating Scale (FRS) [52 weeks]
- Change from Baseline on Modified Alzheimer's Disease Cooperative Study - Clinical Global Impression of Change (modified ADCS-CGIC) [52 weeks]
- Number of study participants who tolerate oral doses of TRx0237 as determined by safety parameter changes [52 weeks]
Safety parameters included adverse events, vital signs, methemoglobin and oxygen saturation, physical and neurological examinations, laboratory tests (hematology, serum chemistry, and urinalysis), electrocardiograms, assessment of serotonin syndrome, brain magnetic resonance imaging (MRI) and potential for suicidal behavior and thoughts
Other Outcome Measures
- Early effect on modified ADCS-CGIC (change from Baseline) [8 weeks]
- Change from Baseline on the rate of atrophy in frontal and temporal lobes as well as ventricular volume (assessed by brain MRI) [52 weeks]
- Change from Baseline on Mini-Mental Status Examination (MMSE) [52 weeks]
- Change from Baseline on Addenbrooke's Cognitive Examination-III (ACE-III) [52 weeks]
- Determine the effect of TRx0237 in subjects with known genetic mutations associated with bvFTD [52 weeks]
